# Drill

## Contract

| Field | Bound contract |
|---|---|
| Trigger | give me an exercise, quiz me, keep it fresh, what am I missing / where are my gaps, or explicit practice/quiz/recall/probe |
| Authority | Reversible local: writes only `PROGRESS.md` at the workspace root; rollback is deleting the lines this run appended. No remote mutation. The file is append-only, never rewritten. |
| Side effect | Appends one line per attempt to `PROGRESS.md` at the workspace root; drives spaced recall and probes gaps. |
| Done | The named move completed; every attempt recorded; cleared concepts marked no-hints-independent. |

## Inputs

- A concept name (required) and a move (optional): `practice`, `quiz`, `recall`, or `probe`.
